Objective: Common carotid artery aneurysm (CCA-AN) is a rare disease. Therefore, an effective treatment has not yet been established. Herein, we report a case of mycotic CCA-AN that was unexpectedly treated by coil embolization with stenting.
Case Presentation: An 85-year-old female who had renal dysfunction presented with painful swelling of the left neck and was diagnosed with mycotic CCA-AN. She underwent carotid artery stenting using overlapped closed-cell stents, which had the anticipated flow-diverting effect. We reduced the amount of contrast medium by using ultrasonography to avoid exacerbation of renal function. However, a partially-uncovered orifice of the aneurysm was identified 5 days after the procedure because of shortening of the stents. Additional coil embolization was performed after the stenting and the aneurysm was completely thrombosed.
Conclusion: We report the case in which a good outcome was obtained by coil embolization as the retreatment for mycotic CCA-AN.
